This apparatus comprises a body (2) having a passage (3) for a product to be sprayed, and a cavity (4) into which a high-voltage generator (21) fits, a high-voltage electrode (27) electrically connected to the generator, and a needle valve (7) for controlling the flow of the product in the passage (3) towards the outlet orifice (6) of the spray head (5). In order for the operations of disconnecting the generator (21) and the needle (8) of the valve (7) to be able to be carried out independently of each other, the passage (3) and the cavity (4) extend as far as the rear end of the body (2) where they emerge into the outside, a removable closure plate (32) is fixed to the rear end of the body (2) and closes off the cavity (4), and a removable bearing element (43) for a spring (17), which urges the control rod (16) of the needle (8) in the closure position, is fixed to the rear end of the body (2). <IMAGE> |
